Application filed March 5, 1919. Serial No. 280,712.

To all whom it may concern Be it known that I, J onnY BnLrnnio, a citizen of the United States of America, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented new and useful Improvements in Reproducers, of which the following is a specification. v

The primary object of the invention is to provide a reproducer for talking machines which is readily adapted for playing diamond disk records, records in which the sound undulations are on the side of the groove and disks in which the sound undulations are in the bottoms of the grooves. To this end the invention comprises a tone arm and a sound box universally connect ed to the tone arm, the sound boxcarrying stylus or a needle attachment for records in which the sound undulations are on the sides and bottoms of the grooves respectively and carrying a diamond for use with a diamond disk record.

invention, the sound box being shown in the.

box for playing diamond disk records.

I mond and the connection between it and the arm.

Fig.9 is a section on the line 99 of V Fig. 5.

Fig. 10 is a section on the line 10-1O of Fig. 6.

Fig. 11, is an enlarged detail sectional view showing the connection between the lever carrying one kind of record engaging element and the arm operatively connecting with other kinds of such elements.

Referring to the drawings, there is shown a tone arm 1 carrying at its smaller end a transverse member 2, loosely surrounding which there is a band portion 3 of a nipple member a, this nipple member 1 carrying a spring operated hook latch 5 by means of which the tubular elbow member 6 is secured to the nipple. Adjacent one this construction provides for securin the tubular member 6 in position in the nipple while allowing it the restricted angular movement referred to.

The sound box'9 employed connects with the short leg 8 of the tubular member 6 by means of a tubular member 10, this tubular member being of flexible material preferably fabric lined rubber, being frictionally attached to the sound box 9 and also frictionally attached to the short leg 8 of the tubular member 6, but being inserted over the latter. This tubular member 10 obviously permits the sound box 9 to be turned angularly in a plane parallel with the longer leg or tubular member 6, for a purpose herein: after appearing.

The sound box 9 supports, as is usual, the diaphragm 11 and this diaphragm carries at its center a plate 12 formed with a globularsocket l tadjacent the diaphragm and a perforation 14 opening from the back face of the plate into the socket. This plate is secured in any suitable'manner to the dia phragm and is designed as the attaching means to the diaphragm of the arm 15 which is operatively or may be operatively connected with the record engaging members of the device. The arm 15 is formed with a substantially right angular bend at one end, this bent or turned end terminating in a ball 16 which engages in the socket 13, a re stricted neck portion 17 connecting the ball with the curved portion of the arm, this neck portion passing loosely through the perforation 14:. This construction will permit the vibrations of the stylus to be communicated to the diaphragm and at the same time will permit the arm to be turned angularly in a plane parallel to the plane of the diaphragm.

The sound box 9 at a specified point is formed with a projecting block portion18 on opposite sides of which the yoke 19 is connected, the yoke being secured in place by screws20 and the particular construction providing for the yoke rocking in the plane of the sound box. The yoke 19 carries means for supporting a stylus as indicated generally at 21 and also carries a projection 22 formed with a slot 23, the slot opening on one side of the projection. Threadingly passed through the projection from the upper or outer face there is a set screw 24, and this set screw may seat against the end portion 25 of the arm 15 when the latter is 0011- nected with the yoke 19 as it will be when the device is used for playing records in which the sound undulations are on the side of the grooves.

At a point 90 degrees or substantially 90 degrees from the projection 18, the sound box is formed with two spaced projections 26 on the outer edges of which there is attached a second yoke 27, screws 28 serving to efi'ect this attachment. Resilient washers 29 are interposed between the yoke and the projections 26, and thus provide for a slight vibration of the yoke when the stylus which the yoke is designed to carry is being vibrated by the sound undulations of the record with which the invention is used. The yoke 27 is formed with a projection 30 similar to the projection 22, and this projection 30 is formed with a slot 31 in which the end 25 of the arm 15 may rest, this projection carrying a set screw for seating against this end 25 of the arm 15 when the latter is connected with the yoke 27. The open sides of the slots 31 and 23 face each other. It will thus be observed that the arm 15 may be swung through an are at ninety degrees to connect with one or the other of the yokes 27 and 22, its ball and socket connection with the diaphragm permitting such angular movement.

Facing the diaphragm and mounted on the sound box diametrically opposite the yoke 19 there is a guard plate or shield 33,

this guard plate overhanging the diaphragm at the center of the latter. It is formed with an opening 34 directly above the point of connection between the diaphragm and the arm 15. On that side of the opening 34: opposite the yoke 19, the guard plate carries two upstanding ears 35 between which there is pivotally mounted one end of a lever 36, resilient washers 37,, preferably rubber, being inserted between the lever and the ears. This lever 36 is formed at its free end with a right angular portion 38 in the end of which is carried a diamond 39 for engagement in the grooves of diamond disk records. A steel wire 40 connects with this lever 36 and has one end seated in an appropriate hole-formed in the arm 15 directly in alinement with the ball 16, so that the arm 15 may be swung from one, yoke to the other without derangement of the lever 36.

In the playing of a record in which the sound undulations are on the side of the grooves, the stylus of the yoke 19 is brought into place and the arm 15v is, therefore, connected with it in the manner hereinbefore described. The tubular member 6 is turned to bring its .shortleg 8 substantially parallel with the record and the sound box is then turned by means of slipping the tubular member 10 around said short leg until the stylus in the yoke 19 is brought in a position to stand vertically or substantially vertical upon the record. The starting of the machine will then permit the playing of the record for which the yoke 19 and its at tendant stylus is adapted for use.

In playmg'records when the sound undulations are on the bottom of the groovesthe tube 10 is slipped angularly around the short leg 8 to bring the stylus of the yoke 19 substantially in the position previously occupied by the stylus of the yoke'19, the arm 15 being shifted over and connected with the said yoke. The sound box is then in position to play the character of record for which the yoke'27 is adapted for use.

When it is desired to play diamond disk records, the tubular member 6 is turned angularly in the nipple 4 until the short leg 8 stands substantially vertical to the record and the tubular member 9 is shifted around the short leg of the tubular member to bring the diamond 39 in a position so that the lever 36 drags upon the record, when the device is useful in. playing diamond disk records.

The invention, having been described what is claimed as new and useful is:

1. A reproducercomprising a tone arm, asound box operatively connectedwith the tone arm for angular movement both in a horizontal and in a vertical plane, a diaphragm carried by the sound box, a pair of spaced record engaging elements disposed on the periphery of the soundbox, a lever pivotally mounted on the sound box and facing the diaphragm, an arm operatively connected with the diaphragm and operatively engageable with either of the record engaging elements on the periphery of the sound boX, a record engaging element carried by the said lever and operative connections between the lever and the arm, said operative connection providing for angular movement of the arm for engaging with either of the aforesaid record engaging elements.

2. A reproducer comprising a tone arm, a

, sound box operatively connected with the tone arm for angular movement both in a horizontal and in a vertical plane, a diaphragm carried by the sound box, a pair of spaced record engaging elements mounted on the sound box at the periphery, a guard plate carried by the sound box opposite the diaphragm and formed with an opening, a lever pivotally mounted on the guard plate and carrying a record engaging element at its free end, an arm operatively connecting with the diaphragm and operatively engageable With either of the first two said record engaging elements, and a Wire operatively connected with the lever and having one end seated in a hole formed in the said arm, whereby angular movement of the arm is permitted for its connection with either of the two first said record engaging elements.

In testimony whereof I afiix my signature.
